    Abstract: A light-emitting device includes a substrate; a lens array having a plurality of lens sections in a matrix pattern; and a plurality of semiconductor laser elements disposed on the substrate. Each of the semiconductor laser elements emits a respective laser beam, each laser beam having a beam shape with a greater width in a column direction than in a row direction on a light incident surface of each respective lens section. The lens sections have an inter-vertex distance in the row direction that is smaller than both (i) a maximum outer diameter of each of the lens sections, and (ii) an inter-vertex distance in the column direction. A curvature of the lens sections in the row direction is the same as a curvature of the lens sections in the column direction.

    Abstract: A light emitting device includes a base defining a recess opening upward, a semiconductor laser element, a light reflecting member to reflect light from the semiconductor laser element, a wavelength converting member to convert wavelength of light from the light reflecting member, and a cover including a light-transmissive member and covering the opening of the recess. The recess is defined in the base by first inner lateral surfaces extending downward from a periphery of the opening of the recess defined in the upper surface of the base, a bottom surface connected to the first inner lateral surfaces, a mounting surface connected to the first inner lateral surfaces and located higher than the bottom surface in a region different from the bottom surface when viewed from above, and second inner lateral surfaces connecting the bottom surface and the mounting surface. The wavelength converting member is fixed on the mounting surface.

    Abstract: A light-emitting device includes: a substrate comprising a base; a semiconductor laser element disposed on an upper surface of the base; a sealing member located above the base and fixed to the substrate, wherein the sealing member and the substrate define a sealed space in which the semiconductor laser element is located; and a lens member fixed to the sealing member by adhesive, the lens member comprising a lens section through which light emitted from the semiconductor laser element passes. A space between the sealing member and the lens member is open to an area outside the light-emitting device.
